更新日志
2.2.53
- Improvement [Whitelist]: Added global AJAX/REST whitelist for WooCommerce and major payment gateways (PayPal, Stripe, Klarna, Mollie, Amazon Pay, Apple Pay, Google Pay, Link) to prevent false CAPTCHA validation during checkout.
- Improvement [Captcha Math Generator]: Improved numeric CAPTCHA validation logic to correctly handle 0 results (e.g., 5 − 5 = 0) and prevent false negatives from empty or non-numeric inputs.
2.2.52
- New [WooCommerce Checkout]: Now protected with Captcha. Enable or disable under Settings Extended. More security. Less spam.
- Improvement [API v2]: Refactored server-side validation for greater consistency and reduced error rate.
2.2.51
- Improvement [API v2/JavaScript]: Refactored client-side validation for consistency and reduced error rate
2.2.50
- Fix [API v2]: Updated key and endpoint configuration.
- Fix [JavaScript]: Adjusted script to align with latest Chrome behavior, resolving issues with event forwarding from WooCommerce/WordPress.
2.2.49
- New [API v2]: Started implementing the new Captcha SaaS solution.
- Fix [JavaScript]: Fixed a bug that prevented WooCommerce from triggering its own events on form submit.
- Fix [Logger]: No longer tied to WP_DEBUG. Enable with F12_DEBUG.
- Fix [Core]: Updated paths for blacklist and set timeout value to 3s.
2.2.46
- Fix [Core]: Removed dynamic property creation in CaptchaTimer; explicit initialization.
- Fix [JS]: Validation now works when the submit button has an inline onclick; our callback is no longer blocked.
- Fix [Gravity Forms]: CAPTCHA now renders at the configured position; misplacement previously caused constant protection triggering.
- Fix [Logs]: Removed properties are no longer tracked; prevents excessive log size growth.
2.2.44
- Fixed: Updated the comparison of
$setting_valueby adding an explicit(int)cast to ensure numeric strings like'1'are correctly converted to integers. This fixes issues where the strict comparison=== 1would previously returnfalse.
2.2.43
- Fixed: Adjusted hooks to clear database entries by user.
- Fixed: Fatal error caused by IPLogs using array_keys
2.2.4
- New: JetForm support
- New: IP Blacklist Validator
- New: Anonymous telemetry (opt-out)
- Improved: Simplified configuration defaults
- Improved: Reload & error handling for form plugins
- Fixed: Admin whitelist for Ajax forms
